Implement open protocol Building Automation System for future multi-vendor expansion.

Monitoring and alarming of Space Temperature within a prescribed limits.

The Ernst & Young is primary concern was a power loss and high space temperatures in the both the data center and LAN rooms. The UPS or generator would start and all A/C units would cycle on and off with no delay and this would put a drain on the power supply. E&Y sought to implement an integrated system that would not only effectively monitor, but also time out and stage the A/C system restart. They were also looking for a system that allowed for future expansion of the remote alarm monitoring.

THE ENERTECH SOLUTION

Implementation of Circon’s Integrated Building Automation System provides integrated monitoring of HVAC.

Alarms monitoring and remote access though the SMC’s. Install Circon controllers in each HVAC unit, UPS, switchgear, and generator unit with both puck & rope type leak detection below raised floors . Each HVAC system has included in it sensors for space temperature, high and low refrigerant pressures, compressor amperages, fan status, filter status, common trouble and water detection. All generator controllers monitor status and run time, all UPS controllers monitor status and battery condition. All switch gear controllers monitor switch position and incoming voltage. HVAC alarms are set up to dial out to a chosen mechanical contractor with 24-hour service and Enertech’s Command Center. All alarms are also routed directly to E&Y command center though the Lon Network. The dial out and remote dial in access gives redundancy to the system. All Controllers and SMC have their own backup UPS device to insure alarm routing incase of power failure. Develop a program to time delay all data HVAC equipment off and pack on when ever power is interrupted to the center. Monitor pump status with automatic lead/lag and emergency switch over.

GE Industrial System’s headquarters in Plainville, Connecticut is comprised of a 10-building complex whichhouses office, warehouse, manufacturing and production space totaling 244,000 sq. ft. over three stories.Both the office and production areas are often occupied at all hours of the day.

Immediate and ongoing reduction in energy consumption and demandIntegrated control of both HVAC and lighting systems – which previously operated as completely independent systemsAbsence of area schedules created unpredictable and uncomfortable space temperaturesMultiple systems to be managed through single central management system Implement open protocol building automation system for future multi-vendor expansion

GE Industrial System’s (GE) primary concern was reducing their energy consumption, not only for the immediatesavings but also to qualify for a Connecticut Light and Power (CL&P) utility rebate for which GE had to proveincreased future energy efficiency. The existing HVAC units, of varying vintage, operated independently which wascostly and needed improvement. As part of the challenge, the lighting system, a significant energy consumer, hadno interaction with the HVAC system. Further, individual area comfort was almost non-existent.GE sought to implement an integrated system that would not only effectively monitor and manage their energyconsumption, and quickly pay for itself in doing so, but also allow for future expansion.

Circon controllers installed in 33 rooftop units and 280 lighting circuits are connected together to create a complex-wide LonWorks network. The system is configured with more than 30 zone schedules, each tailored to meet the needs of individual departments within the facility. Zone schedule adjustments affect both HVAC and lighting systems and reduce occupancy overrides resulting in increased comfort levels and energy savings.The HVAC controllers contribute further to reduced energy consumption by monitoring outdoor air vs. indoor air enthalpy and take advantage of “free cooling” opportunities during the milder months. Circon BASIC language used to program the sequence of operations for many of the controllers, allows HVAC and lighting systems to operate at peak efficiency and optimize the load handling around the clock.GE Industrial Systems realized an immediate increase in control of their building automation system. Circon’s Visual Integrator™ software, with point and click maneuverability, provides an easy to use central managementsystem for GE’s in-house facility managers. Visual Integrator allows total monitoring control, with the capability to view real time information and to change operating schedules of systems and devices. The system can be programmed, maintained and supported remotely.

For future expansions GE will be able to receive competitive bids for maintenance, service and system additionsbecause of Circon’s open protocol building automation system in place today.

It was established that the implementation of this system would save approximately 1.3 M Kilowatt-Hours annually. As a result, GE would qualify for a CL&P utility rebate in excess of $70,000.CL&P verified by runtime audit and computer simulation that there was an energy reduction on the controlled equipment. Calculations are outlined below.

HVAC S U B S Y S T E MCL&P used computer simulation based upon data such as: type of area (office, warehouse, production), percent occupancy and types of controls employedThe utility determined that based upon data provided and their audit, more than 500,000 KWH would be saved annually

Conservative estimates for annual savings for the controlled rooftop AC units and the lighting circuits areapproximately 1.3M KWH per year. At an approximate rate of $0.06 per KWH, this yields an annual dollarsavings of $ 78,000 per year. This savings represents a payback period of 1.96 years – with the CL&P rebatefactored in the payback period is 1.1 years.

Jersey City Museum is located in Jersey City, New Jersey. It is comprised of one building, which was originally built in 1929. It now consists of an art vault, six new galleries, art classrooms, offices and an auditorium. It now serves a broad and diverse urban community by maintaining, preserving and interpreting the region’s cultural heritage. The new facility was completed in December 2000 and officially opened on October 19, 2001.

The Time Warner Cable of New York primary concern was a power loss at any of the unmanned hub site. The Generator would start and operate until someone would acknowledge the city power had returned. On a few occasions, the Generator had run out of fuel. TWC would not know of the power failure until cable was lost to the area served by that hub site.TWC sought to implement an integrated system that would not only effectively monitor, but also allow for future expansion of the remote alarm monitoring.
